REACTIONS DE SUBSTITUTION SRN1 EN SERIE QUINONIQUE

Crozet, Michel P.,Jentzer, Olivier,Vanelle, Patrice

, p. 5531 - 5534 (1987)

Salts derived from 2-nitropropane react with 2-(halomethyl)-9,10-anthracenedione or triethylammonium derivative by a SRN1 mechanism.The operation of this mechanism is confirmed by the leaving group effect and by the inhibitory effect of di-tert-butylnitroxide.A base-promoted nitrous acid elimination gives a 9,10-anthracenedione bearing a trisubstituted ethylenic double bound in the 2 position.
